Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in components shipped |
| 19 |
with LTSP which allow remote attackers to compromise terminal clients. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Linux Terminal Server Project adds thin-client support to Linux |
| 25 |
servers. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 net-misc/ltsp < 5.0 Vulnerable! |
| 34 |
------------------------------------------------------------------- |
| 35 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 36 |
to another package if one is available or wait for the |
| 37 |
existing packages to be marked stable by their |
| 38 |
architecture maintainers. |
| 39 |
|
| 40 |
Description |
| 41 |
=========== |
| 42 |
|
| 43 |
LTSP version 4.2, ships prebuilt copies of programs such as the Linux |
| 44 |
Kernel, the X.org X11 server (GLSA 200705-06, GLSA 200710-16, GLSA |
| 45 |
200801-09), libpng (GLSA 200705-24, GLSA 200711-08), Freetype (GLSA |
| 46 |
200705-02, GLSA 200705-22) and OpenSSL (GLSA 200710-06, GLSA 200710-30) |
| 47 |
which were subject to multiple security vulnerabilities since 2006. |
| 48 |
Please note that the given list of vulnerabilities might not be |
| 49 |
exhaustive. |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A remote attacker could possibly exploit vulnerabilities in the |
| 55 |
aforementioned programs and execute arbitrary code, disclose sensitive |
| 56 |
data or cause a Denial of Service within LTSP 4.2 clients. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
LTSP 4.2 is not maintained upstream in favor of version 5. Since |
| 67 |
version 5 is not yet available in Gentoo, the package has been masked. |
| 68 |
We recommend that users unmerge LTSP: |
| 69 |
|
| 70 |
# emerge --unmerge net-misc/ltsp |
| 71 |
|
| 72 |
If you have a requirement for Linux Terminal Servers, please either set |
| 73 |
up a terminal server by hand or use one of the distributions that |
| 74 |
already migrated to LTSP 5. If you want to contribute to the |
| 75 |
integration of LTSP 5 in Gentoo, or want to follow its development, |
| 76 |
find details in bug 177580. |
